There's no problem between Vinicius and Mbappé. This is just news that's been constantly pushed by the media without any clear explanation or evidence. It's simply because Real Madrid's attack played poorly last season, leading many to speculate that Vinicius and Mbappé don't have a good relationship. But I don't think so.
I'm also confident that Vinicius and Mbappé won't be sold; this is Real Madrid's long-term plan for their attack.
Under Xabi Alonso, we don't know what strategy he'll employ, but what's certain is that Vinicius and Mbappé will remain in their positions and both will continue to play in Real Madrid's starting lineup.
Yep, both are supporting each other.
It's the fans who make the situation looks bad, the same thing happened to Ronaldo and Messi, both were very supportive, but people are hating each other to feel their own satisfy.
Vinicius was fine with his new role to support Mbappe, but we don't know for the upcoming season with Xabi's strategy, as we can see in Club World Cup, Xabi place Mbappe in his main position as a left winger, then he place a real striker in center forward.
